Relative dating does not offer specific dates, it simply allows to determine if one artifact, fossil, or stratigraphic layer is older than another. Absolute dating methods provide more specific origin dates and time ranges, such as an age range in years.

Why is relative and absolute dating a useful tool in determining the subdivisions of geologic time scale?

Scientists use the geologic time scale to illustrate the order in which events on Earth have happened. They used relative dating to divide Earths past in several chunks of time when similar organisms were on Earth. Later, scientists used absolute dating to determine the actual number of years ago that events happened.
